To (ZZZ whom e'tmay concern.

'Be it .known that I, CLARANOE' CHARLEs VVELLs, a citizen of the UnitedStates, residing at Fort l/Vorth, in the county of Tarrant and State ofTexas, have invented a new and useful Composition of Matter forthe Weld-'ing and Soldering of Articles Constructed of Aluminum. I

My composition consists of the following ingredients, combined instated, viz:

Aluminum 1 part. 1 Lead 3 parts.

Block tin .7 parts.

Zinc 2 parts.

. in such a molten state as to mingle freely,

and become one molten mass. ent ingredients after. be ng melted andthormighly mingled by agitatmn and while sun in the molten form istreated four to seven times With muriatic acid of strength thirty-twoper cent. pure, theacid being poured into the composition to purity andcleanse the same; the acid after evaporation leaves the sediment anddirt in the com position floating on the surface, which sediment anddirt is skimmed from the surface leaving the composition ure and cleanand ready to be poured into 'orms or molds suitable to themanul'acturer; The-quantity of muriatic acid used in the process of,

be freed from all dirt and obstacles by brushing the ends to be welded,or the surface to the proportions canon Specification of Letters Patent.Patented Sept, 11, 191 Application filed June 23, 1917. Serial210.176,.235.

besoldered with a steel wire brush. The

composition to become soft and doughy when it is worked into the desiredshape to correspond with the ends being welded,

after which the Work-is allowed to cool and g is ready for use.

By the use of the above composition the crystallization of aluminum wereis avoided in the process of welding or soldering as it only requiresseven or eight hundred degrees of heat to place it in proper shape forwork, whereas under other processes of welding andsoldering articlesconstructed of aluminum by the acetylene process there is required aheat of from twenty-five hundrcd to thirty-five hundred degrees, whichcauses aluminum to crystallize and weakens it. as aluminum will onlystand about fourteen to fifteen hundred degrees of heat. The compositionherein is stronger than aluini num and has an elasticity and flexibilitynot common in aluminum articles, does not injure the metal to which itis applied, as itmelts at a low temperature, and avoids the effect ofcrystallizing the article being worked upon.

I am aware that a composition consisting of aluminum, lead, block tin,zinc, bismuth and antimony have been used for the same purpose, and"that a patent therefor was granted to one Robert Lee Weatheriord,

August 8th. 1916, No. 1,19 l,101;but I am not aware that all the'ingredientsmf my composition and my process of manufae ture have beenusedtogether.

' I claim:

The herein descrioeu composition for welding and soldering articlesconstructed oi. aluminum, consisting of aluminum one part, lead threeparts, block tin seven parts and zinc two parts. substantially asdescribed.
